Perhaps you should try some spelling variations:
"a regulatory properties" » "a regularity properties", "a regular properties", "a regulatory perspectives"
"key regulatory practice" » "key regulator practice", "key regulators practice", "3 regulatory practice", "key regulatory practical"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("key regulatory practice") OR ("a regulatory properties"))*.
• Removing quotes may allow a broader search: (( key regulatory practice ) or ( a regulatory properties ))*.
